I have a plastic water line in the back, and a water filter inside the fridge connected to the water line near the top right. The filter looks exactly like this:
After I bought the filter, and replaced the old one in the fridge according to the instructions provided with the filter, the water dispenser started dispensing water very slowly. If I twisted the filter a little bit while dispensing the water, then the water came out a little bit faster, but still not the normal water flow. Same thing happened when I pulled on the filter a little bit while dispensing water...faster, but still not the normal water flow.
After digging a little deeper trying to find some information on how to fix this thing, I discovered a few threads:
Basically, the idea was to put a rubber washer in with the water filter, so that the water would flow normally. I didn't quite understand why this would work, but I finally figured it out.
So, here's a picture of the water filter part that's inside the fridge. I took a picture of it by sticking my iphone inside the fridge and turning it upside.
I wanted to see what the thing looked like when the water filter was taken out. The actual water filter cylinder connects to the image above. Now, do you see that little black thing on the left side? Well, that little thing is kinda like a stopper. When the water filter is connected to it, the little black thing pushes upwards and allows the water to flow into the filter. It's cheap and it's plastic, which is why I think so many people have problems with their water dispensers.
Now, here's what I did. I found a washer in my toolbox:
I placed the washer in my water filter. Here's a picture of them both next to each other:
Here's a picture of just the water filter top:
If you look at the top of the water filter where the water enters, you'll notice two little wedge things. These two wedge things push that little black piece upwards, so that the water can flow into the filter. Since the little black thing is plastic and cheap, it doesn't take much for it to break and/or split and NOT push all the way up allowing full water flow into the filter, thus causing your water dispenser to flow slowly.
So, after I put the washer into the water filter, and reconnected the water filter to the fridge, it helped, but it still didn't fully work. I had stick a small screw driver into the fridge connection and kind of "sharpen" the little black thing, so that it would protrude a little more. This allowed the little black thing to push up higher, allowing more water flow.
I know it's confusing, but it worked for me. Basically, if you're not getting good water flow from your water dispenser, it's most likely because the water flow into the filter is being limited by that little black thing.
